SPRING SHADE-ROLLER.

SPECIFJ ICATION forming part of Letters Patent No. 417,783, datedDecember24, 1889.

- Application filed November 8, 1888. Serial No. 290,305. (No model.

To all whom it may concern.-

Be it known that I, STEWART HARTSHORN, a citizen of the United States,and a resident of Short Hills, in the county of Essex and State of NewJersey, have invented certain new and useful Improvements in SpringShade-Rollers, of which the following is a full, clear, and eXactdescription, reference being had to the accompanying drawings, making apart of this specification.

My improvement relates to the end cup or plate on the end of the roller,which supports the outer end of the spindle and forms the bearing of theroller on the spindle when the roller is operated; and it consists in anovel construction of the end plate and manner of supporting the spindleby the same, and of forming the bearing of the roller on the end of thespindle; and it also consists in a cheap and simple manner ofconstructing the end plate itself.

In the drawings illustrating my improvement, in which like lettersindicate like parts, Figure l is a view of the outer face or front sideof my improved disk. Fig. 2 is a view of the inner face or back of myimproved disk, showing the cup or ferrule in which the end of thespindle rests. Fig. 3 is a detached View of the disk and spindle cup orferrule. Fig. 4 is a sectional view of the disk or plate, showing theouter end of the spindle in position in the cup or ferrule. Fig. 5 is asectional View of the end of the complete roller, showing the spindlewith the spring mounted on the same resting in or supported by the cupor ferrule 011 the end plate.

As heretofore constructed and arranged, the spindle on which the springis mounted is supported or held at its outer end by the spear or smallsection E, which passes through the end plate and is inserted into thespindle, and whose outer end engages with the bracket on which theroller is mounted. This spear or section E rests on the edge of the holein the plate through which it ,passes. Hence, when the roller is mountedin the brackets and is operated, as the roller revolves around the fixedor stationary spindle, the point of bearing of the roller on the spindleis the narrow edge of the small hole in the plate and the spear or smallsection E of the spindle.

In my improvement the spindle is supported directly by its outer end,which rests in a projecting cup or ferrule on the inner face of thedisk, and the spear, as it passes through the hole in the center of thedisk, does not rest on or come in contact with the latter.

The nature of my improvement will be best understood by reference to thedrawings, Figs. 4 and 5 of which show the position of the various partswhen in place and connected together. As there seen,the end of thespindle D rests in and is supported by the cup or projecting ferrule O,which is connected to the back or inner face of the disk A, and thespear E as it passes through the hole 13 in the disk does not touch theedge of the latter. The diameter of the cup 0 is a little greater thanthat of the spindle, so that the latter rests loosely in the cup and yetdoes not have any play up or down as the roller revolves around it. Thediameter of the cup is therefore greater than that of the hole Bin theplate, as the latter must be smaller than the spindle in order to holdthe spindle in the roller. The bearingsurface, therefore, is greaterthan where the spindle is supported by the spear on, the hole in theplate; and, moreover, as the cup 0 projects inward some distance fromthe plate, it offers a much longer bearingsurface than Where the spindleis supported by the thin narrow plate or disk itself.

\Vhen the roller is put together ready for use, as shown in Fig. 5, theouter end of the spindle D within the roller is placed in the cup orferrule (J, so that the end of the spindle itself rests in or issupported by the inner surface of the cup, and the spear E passesthrough the large hole B in the plate A, so as to clear the edges ofsame and not touch the plate. The spring S is mounted on the spindle inthe usual manner, and is attached to the plate A by means of the lugs F,or in any other convenient manner. As the roller revolves in itsbrackets around the fixed or stationary spindle, as will be understood.from the drawings, the bearing of the roller is on the inner surface ofthe revolving cup O and the end of the spindle, which presents a broadtrue bearing, insuring a perfect operation of the roller. Moreover thebearing is on the spindle itself and not on the small outer section orspear E. Hence by my improved mannerof supporting the outer end of thespindle or forming the bearing of the roller or the spindle alonger andmore perfect hearing is formed, thus insuringa more even and truerevolution of the roller, and all eccentricity of the roller caused bythe spear or section E not being inserted in the center of the spindleis prevented, and all consequent Wearing and rattling of the partsstopped.

My improved disk, with the cup O, maybe constructed in anyconvenientmanner, and the cup and disk may be cast in one piece, if desired; but Iprefer the construction shown,

in the drawing. As there shown, and particularly in Figs. 1, 2, and 3,the disk or plate A and cup 0 are formed separately, and are stamped orstruck up from suitable metal, and are then fastened together. The plateA is struck up from a thin disk of metal, as iron, complete, with thecentral hole B, the rim a, lugs F for attaching the ends of the spring,and small holes L, for mounting the paWls P or other locking device. Thecup 0 is likewise stamped from a thin piece of brass or other suitablemetal, and of the required size for the spindle. One end of the cup, asc, is made smaller to-enter the hole B in the plate. The parts, havingbeen thus formed separately, are united byinserting the small end 0 ofthe cup into the hole B in the plate and fastening it there by turningover the edges, as will be understood from Fig. 4:. The end plate ordisk thus constructed is readily and cheaply made, and once formed doesnot require any further manipulating to perfect it and, adapt it foruse.

\Vhat I claim as new is 1. In spring shade-rollers, the combination,with the end plate or disk having a large hole in the center of the sameand provided with a cup or ferrule rigidly attached to the disk,constructed to rest and revolve on the end of the spindle, of thespindle resting in the cup or ferrule and supporting the disk androller, and having a spur passing freely through the hole in the plateor disk, substantially as and for the purposes set forth.

2. In spring shade-rollers, the end plate or disk, formed of the disk A,struck up from metal, and having the central hole B, holes L, and lugsF, and provided with the cup or ferrule 0, adapted to be inserted in thehole 13, and attached to the disk and constructed and arranged toreceive the end of the spindle and rest and revolve on the same,substantially as and for the purpose set forth.
